Ivalve yenaliti yinxalenye ebalulekileyo yesixokelelwano sombhobho womlinganiselo wesixhobo, kwaye sisivalo esikwaziyo ukulungelelanisa ngokuchanekileyo kwaye sinqumle ulwelo.Undoqo wevalve yicone ebukhali kakhulu, esetyenziswa ngokubanzi ukuhamba kancinci, igesi yoxinzelelo oluphezulu okanye ulwelo.Ubume bayo bufana nevalve yeglowubhu, kwaye umsebenzi wayo kukuvula okanye ukusika ivalve yokufikelela kwimibhobho.
1. Indawo yokuvula kunye nokuvala i-valve yenaliti yi-cone ebukhali, ejikelezayo xa ivula kunye ne-clockwise xa ivala.
2. Ubume bangaphakathi bufana nelo valve yokumisa, zombini i-inlet ephantsi kunye ne-high outlet.Isiqu sevalve siqhutywa livili lesandla.
Umgaqo wesakhiwo sevalve yenaliti
1. Ivalve yenaliti enesigqubuthelo sevalve kufuneka ikhethelwe inkqubo yombhobho kunye nesixhobo sobushushu obuphantsi.
2. Kwinkqubo yombhobho yeyunithi yokuqhekeka kweyunithi yeyunithi yokusulungekisa i-oyile, ivalve yenaliti yokunyusa inokukhethwa.
3. Iivalvu zeenaliti ziya kwenziwa ngentsimbi eqinileyo yeaustenitic ene-PTFE njengeringi yokutywina yesitulo sevalve kwizixhobo kunye neenkqubo zemibhobho enosasazo olunoburhalarhume olufana neasidi kunye nealkali kwinkqubo yemichiza.
4. Isinyithi ukuya kwintsimbi yokutywina iivalve zenaliti zinokukhethwa kwiinkqubo zemibhobho okanye izixhobo zemidiya ephezulu yobushushu kwiinkqubo zetsimbi, iinkqubo zamandla, izityalo zepetrochemical kunye neenkqubo zokufudumeza ezidolophini.
5. Xa kufuneka ummiselo wokuhamba, igiya leentshulube eliqhutywayo, i-pneumatic okanye ivalve yenaliti yombane enokuvulwa okumise okwe-V ingakhethwa.
6. Isivalo senaliti esinombhobho opheleleyo kunye nesakhiwo esipheleleyo sokuwelda siya kusetyenziswa kumbhobho oyintloko we-oyile kunye negesi yendalo, umbhobho oza kucocwa kunye nombhobho ongcwatyelwe phantsi komhlaba;Kwabo bangcwatywe phantsi, ivalve yebhola enoqhagamshelo olupheleleyo lwe-welding okanye uqhagamshelo lweflange luya kukhethwa.
7. Ivalve enaliti edityanisiweyo yeflange iya kukhethwa kumbhobho wokuhambisa kunye nezixhobo zokugcina zeoyile yemveliso.
8. Kwimibhobho yerhasi yasezidolophini kunye negesi yendalo, iivalve zenaliti ezinoqhagamshelo lweflange kunye noqhagamshelo lwentambo yangaphakathi zikhethiweyo.
9. Kwinkqubo yombhobho we-oksijini yenkqubo ye-metallurgical, i-valve yenaliti enonyango olungqongqo lwe-degreasing kunye nokudibanisa kwe-flange kufuneka kukhethwe.
10. Ivalve yenaliti yenziwe ngumzimba wevalvu, ikhowuni yenaliti, ukupakishwa kunye nevili lesandla.
